Zotero allows you to easily create collections in order to organize your research citations.
NOTE: Moved items will still appear in the center column of the My Library collection.
When creating collections from Zotero.org, you click the Add Collection button to create both collections and subcollections.
In the following example, we are adding a subcollection titled "Statistics" to the "Social Work" parent collection.
If you're regularly using more than one computer or device in your research, Zotero's sync feature can keep your library up to date on all of them. Zotero can store a copy of your library on the Zotero.org server and check it for updates whenever you open your library on a different computer.
These should match the list of citations from your Zotero Standalone. The initial syncing should happen within a few minutes, if you do not see your citations included try refreshing your browser cache and reloading the page.
